At the start of 1972, Lowrys Hobbies was a successful mail-order store for wargamers. However, the catalog was going out of date faster than it could easily be revised, so a supplement with updates and corrections was provided.
It also contained a short editorial giving news about the business, and two articles. In the normal course of events, it would have started picking up more articles, and expanded until it became an actual magazine.
Instead, Panzerfaust was purchased from Don Greenwood just a few months later. Lowrys Guidon ran for nine issues, and did pick up more content, but was mostly a catalog supplement the entire time.
